Welcome

The Waterloo Fractal Coding and Analysis Group (which originated from the "Waterloo Fractal Compression Project" that used to be located at this website) is comprised of a group of researchers who have been interested in various aspects of fractal analysis including: iterated function systems, fractal image coding, generalized fractal transforms and the inverse problem of approximation using fixed points of contraction mappings.

Image Repository

Our Image Repository provides a diverse suite of image data. Greyscale and color images of different sizes are available in several image formats.

This set of images was formally part of the BragZone repository, which provided a quantitative comparison from a diverse set of image compression programs.
